Soil Taxonomy

"The publication Keys to Soil Taxonomy serves two purposes. It provides the taxonomic keys necessary for the classification of soils in a form that can be used easily in the field. It also acquaints users of the taxonomic system with recent changes in the system. The eleventh edition of the Keys to Soil Taxonomy incorporates all changes approved since the publication of the second edition of Soil Taxonomy: A Basic System of Soil Classification for Making and Interpreting Soil Surveys (1999). One of the most significant changes in the eleventh edition is the addition of the suborders Wassents and Wassists for subaqueous Entisols and Histosols. We plan to continue issuing updated editions of the Keys to Soil Taxonomy as changes warrant new editions. Since it was first published 35 years ago, Soil Taxonomy: A Basic System of Soil Classification for Making and Interpreting Soil Surveys has been used to support soil survey efforts in many countries around the world. It has been translated into several languages. Soil scientists from many nations have contributed significantly to the development of the taxonomic system. The authors encourage the continued use of soil taxonomy internationally and look forward to future collaborations with the international soil science community so we can continue to make improvements. Through continued communication and collaboration, we hope that our efforts will eventually result in a truly universal soil classification system."
